Several beneficial effects for allantoin as an active ingredient are described for cosmetics use, including:

When sold on its own for use in homemade soaps, lotions, and bath products, allantoin is a white, crystalline powder.
It is moisturizing and keratolytic, meaning that it causes keratin in the skin to soften. This enables the skin to heal more quickly and to bind moisture more effectively, making products containing this substance useful for dry skin and for healing wounds, burns, and scars.
It is also effective against sunburn, chapped lips, cold sores, diaper rash, and similar skin irritations.
